Abstract
The present application presents a method and an apparatus for synchronizing time by parsing satellite navigation data. A service application obtains current time of a system and caches it as a first time variable, receives and parses the satellite navigation data to obtain all character strings, obtains a character string as a current character string to be processed, determines a type of a system protocol identifier, if it is a preset system protocol identifier, converts a time field of the current character string to be processed into a local time zone time value for storing, obtains the current time and stores it as a second time variable, obtains a first time compensation value according to the first and second time variables, obtains satellite navigation time according to the first time compensation value and the maximum local time zone time value and sets system time as satellite navigation time.
